10. FUMARIA PARVIFLORA. Plate 191 
Fumaria parviflora Lamarck Encycl. Method, ii, 567(1 786) 1 ; Hammar Mon. 16, t. 2 (1857) ; Haussknecht 
in Flora lvi, 456(1873); Rouy et Foucaud FI. France i, 181 (1893); Pugsley Fum. Brit. 60(1912); F. tenuisecta 
subsp. parviflora Syme Eng. Bot. i, 1 14 (1863). 
Annual. Shoot glaucous. Stem generally robust, suberect, diffuse or occasionally climbing. 
Leaves mostly tripinnatisect ; leaflets cut into linear 
and generally acute lobes ; lobes normally channelled 
but flattened and elongate in shade. Racemes dense 
when young, becoming lax in fruit, less than 20- 
flowered, subsessile or very rarely shortly peduncled. 
Bracts broad, linear-oblong, cuspidate, often serrate 
above. Pedicels about as long as or sometimes shorter 
than the bracts, thickened, straight and suberect in 
fruit. Flowers May to September. Sepals minute, 
incise-dentate or laciniate, acute, about ro — 1*5 mm. 
long and o'65 — 075 mm. broad. Corolla white or 
flushed with pink, the tip of the inner petals blackish- 
red and usually with a contiguous external dark blotch 
at the base of each wing of the upper one, 5 — 6 mm. 
long ; upper petal broad and much dorsally com- 
pressed with a flattened green keel, truncate with 
spreading (rarely erect-spreading) or occasionally de- 
flexed wings reaching the apex ; lower petal ovate- 
spathulate with spreading margins. Fruit subrotund 
or subrotund-ovate, with little lateral compression but 
a distinct keel, mucronulate or shortly beaked ; neck 
obscure, as broad as the tip of the thickened pedicel ; 
when dry, granular-rugose, with obscure and shallow 
apical pits; rather small, 2 - o — 27 mm. long and about 
2 mm. broad.

leones: — Reichenbach Icon. (Papav.) t. 1, fig. 4451, as F. parviflora ; Sturm Deutschl. Flora i, 62, 16, as 
F. parviflora. 
Exsiccata : — Fiori et Beguinot (Ft. Ital. Exsicc .) ii, 1051, as F. parviflora ; Heldreich {Herb. Graec.), 1206, 
as F. parviflora f. umbrosa. 
Shoot robust, rather lax, generally diffuse or climbing, more or less glaucous. Sepals broadly 
ovate or sometimes nearly orbicular, 1 mm. long and o - 65 — 075 broad. Corolla generally white, 
only occasionally tinted with pink. Fruit subrotund, rounded-obtuse above with the keel drawn 
into a short mucronulus, little more than 2 mm. long and equally broad. 
This variety seems to be constant, and not a forma dependent on environment. Presumably it is the plant originally 
described by Lamarck {toe. cit.). 
Not common; from Dorset to Edinburgh. 
Widely spread on the continent of Europe.

Shoot dwarf, compact, usually suberect, intensely glaucous. Leaves with fine, sometimes sub- 
capillary segments. Sepals as in var. leucantha. Corolla generally suffused with pink ; upper petal
